A sodium–sulfur (NaS) battery is a type of molten-salt battery that uses liquid sodium and liquid sulfur electrodes. This type of battery has a similar energy density to lithium-ion batteries,and is fabricated from inexpensive and low-toxicity materials. Due to the high operating temperature required (usually between 300 and 350 °C), as. During the discharge phase, sodium at the core serves as the , meaning that thedonates electrons to the external circuit. The sodium is separated by a Purepresents a hazard, because it spontaneously burns in contact with air and moisture, thus safety features are required to avoid direct contact with water and oxidizing atmospheres. Grid and standalone systemsNaS batteries can be deployed to support the electric grid, or for stand-alone renewable powerapplications.
Sodium–sulfur batteries operating at a high temperature between 300 and 350°C have been used commercially, but the safety issue hinders their wider adoption. Here the authors report a
